Maybe. Or maybe not. It could apply only to hosts connected via the same switch? Or same AP? That's how i read link-local. It's obvious to you because you already know.

So point me to an overview of ipv6, enough to manually configure a small network, that is clear and complete. Not the RFCs please, I don't want to learn to configure an enterprise (or university) network.
Yes link-local is only local to the link (same broadcast domain).
But most home networks are bridged on layer 2 anyway.
IPv6 allows for a design where you don't have everything on the same broadcast domain but actually use subnets for e.g. the WiFi network. But since you still want to retain IPv4 compatibility, this is usually not an option in home networks.

Just enable router advertisements on your router (likely already the case) to announce a /64 prefix that was derived from the prefix you got from your ISP. You also want to enable RDNSS so DNS server information is included with the router advertisement. (also usually the default)
Then enable SLAAC on your hosts (already the default) to automatically select an address based on the prefix from the router advertisement. A /64 is big enough that the router doesn't have to individually assign addresses. Hosts can just pick one and if they are polite, ask if it's already used by someone else (duplicate address detection).

Last time I searched for one there wasn't one.
